WILLIAM K. HENRY, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE AMERICANHARDWARE CORPORATION, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OFCONNECTICUT.

DOUBLE-ACTING DOOR-CLOSER HINGE.

To all whom it may concern:

Be it known that I, VILLIAM K. HENRY, a citizen ot' the United States,residing at New Britain, county of Hartford, State of Connecticut, haveinvented certain new and useful Improvements in Double-ActingDoor-Closer Hinges, of which the following is a full, clear, and exactdescription.

This invention relates to closer hinges for doors and the like of thedouble acting type and is designed to provide a very inexpensivestructure of this character for application to doors swinging in bothdirections. The closer hinge of the present invention is designed toautomatically return the door to closed position when opened in eitherdirection and is also provided with means for locking the door opened ineither direction. rlhese and other advantages are fully described in thefollowing speciiication takenin connection with the accompanyimg`drawings forming part thereof and illustrating preferable embodiment ofthe invention.

In these drawings: Figure 1 is a tragmentary view ot' the lower portionof a door having my improved closer hinge applied thereto, parts beingshown in section. F ig. 2 is a horizontal section taken on the line 2-2of Fig.V 1. Fig. 3 is a fragmentary vertical section through the partsshown in Fig. 1, and Fig. t is a view in elevation of the pivot memberand its cam arms.

Referring to the drawings by numerals, 1 indicates a door and 2 itscasing.

3 represents a plate designed to be secured to the floor or threshold ofthe door beneath the lower edge of the same. This plate 8 is designed tocarry a pivot member having its extreme upper end l rounded and alsohaving its lower end 5 rounded but reduced at its extremity 6 to form asquare plug which tits within a squared aperture formed in the plate 3,and may be, and preferably Yse is, upset thereagainst. At the upper eX`tremity of the portion 5, the pivot member is shouldered outwardly toform an enlargement 7. Between this enlargement 7 and the upper end el:of the pivot member, the pivot member is reduced to form an intermediatetlat body portion 10 from the upper and lower sides of which extendtransverse webs 8 and 9. The central portion Vof the web 9 is enlargedto form a bearing head 11 which has a groove formed in its upper face inwhich are seated a plurality of balls 12,

lhe upper grooved tace ot` this web 9 constituting therefore a ballrace. Between the alined outer ends of the webs 8 and 9,

'anti-friction rollers 13 are journaled, these cessed to receive theparts coperating with the pivot member and its cams. A bar 14 is securedto the inner under face of the recessed portion of the door and isprovided at one end with a transverse extension or crossbar 15. A bottombar 16 is secured to t-he lower edge of the door and to the end ofcross-bar 15, and has its inner end formed with a transversely extendingportion 17 secured to the inner face of the door and to the inner end ofthe bar (14:, these parts forming a frame. The inner ends of the bars 14and 16 are provided with alined elongated slots 18. A plunger 19 islocated within the recessed portion of the door between the door and thebottom plate 16, this plunger 19 extending longitudinally of the loweredge of the door and through an aperture formed in the cross-bar 15. Therear end of this plunger 19 is enlarged and of friction rollers 13carried by the transverse lwebs 8 and 9 of the pivot member. The rear.end of the yoke 2O constitutes a cross-head which normally bearsagainst the two antifriction rollers 13-13 when the door is closed, saidantifriction rollers operating as cams to force the yoke rearwardly whenthe door to which the apparatus is applied is opened in eitherdirection. The outer end of the plunger 19, which may be in the form ofa flat bar, has its edges threaded as at 21, and a coiled spring 22 ismounted thereover, one end of said spring engaging the cross-bar 15 andthe other end abutting against the flange of a tensioning nut 23 whichhas a threaded engagement with the threaded end of plunger 19. Thetension of the coiled spring 22 acts through the abutment aorded by itstensioning nut to move the yoke 2O against the cam rollers of the pivotmember.

The inner end or cross-head portion of yoke 20 is providedwith anextension 24 which carries rigidly a stud 25 having reduced ends 26fitting within the alined Aslots 18 of the frame carried by the door. vThe yoke 20 is normally pressed by its spring to bring its inner faceagainst the cam rollers of the webs 8 and 9 of the pivot member. The barlet of the door frame is apertured to fit over the upper end l of thepivot member' and `iournal the door thereon, the under face of said baradjacent its pivot resting on the ball race 12 and the upper face of thebottom bar 1G resting against the shoulder formed by the lower edge ofnthe enlargement 7 of the pivot member'.

The contacting edge of the yoke is formed with a central locking recess27 of a curvature corresponding substantially to that of the cam rollers1S, and is curved outwardly from either side of said recess and isformed at its extremities with flat portions 2S against which the camrollers are held by the spring 22 when the door is closed.

It will be obvious that the door 1 is journaled on the upper end of thestationary pivot member and that as said door swings, the frame carriedthereby together with the plunger 19 and its yoke, will move relative tothe stationary pivot member. lVhen the door is in central or closedposition, the parts will be in the position shown in Figs. 1 and 2 ofthe drawing. In this position the anti-friction cam rollers 13 will restagainst the flattened ends 28 of the contact edge of the yoke, thepressure of the spring tending to hold these edges firmly against thecam rollers and, therefore, tending` to center the door in closedposition. Wlhen, however', the door is swung open in either direction,one of the cam rollers 13, being stationary, will engage the contactedge of the yoke as the latter moves relative thereto with the swingingof the door, and, as the door continues to swing, will ride over thecontact edge of the yoke 20, the plunger 19 being moved inwardly tocompress the spring 22 which forms the closer spring. If the door is notentirely opened the compressed spring will act to return the parts tonormal door closed position. If, however, the door is fully opened, thelocking recess 27 of the yoke 2O will snap over one of the cam rollers13 when the door reaches fully opened position, locking the door infully opened position by reason of the setting of a cam roller in thisrecess and the pressure of the compressed spring against this camroller. The door may be closed by moving the same inwardly until thelooking recess 27 of the yoke is moved from engagement with itscooperating cam roller whereupon the force of the compressed closerspring 22 will return the parts to normal door closed position, the doorbeing centered in this position by the engagement of the two cam rollerswith the contact edges 28 of the yoke hereinbefore referred to. Duringthe opening of the door and the consequent swinging of the yoke, theside bars of the yoke remain out of contact with the free cam roller orthat cam roller which is not in engagement with the contact edge of theyoke.

The parts described may be readily and comparatively cheaplymanufactured and require but a minimum amount of machine work. The framecarried by the door and composed of the bars 14, 15, 16 and 17 may beand preferably are of wrought iron. The plunger 19 and its yoke 20 maybe readily cast as well as the Hoor plate and the body of the pivotmember, so that it is apparent that substantial economies in manufactureare eected by the construction set forth. lt is of course understood,that, as is usual in devices of this character, the upper inner edge ofthe door is provided with a pin which is adapted to be seated in asocket formed in the upper casing of the door. The parts of the closerhinge are preferably first assembled and then secured to the inner edgeof the door, and the door then moved to bring its upper pivot pin in itssocket and the lioor plate 8 of the closer hinge to that point on thefloor or threshold which will bring the pivot member 3 thereof inalinementwith the upper pivot pin, whereupon said pivot plate may besecured to the Hoor.

While I have described and shown herein a specific embodiment of theinvention, various structural modicatios are still possible within thespirit of the invention and the scope of the appended claim.

lhat I claim therefore, and desire to secure by Letters Patent is:

ln a double-acting door hinge and closer, a stationary pivot stud, apair of oppositely arranged eccentric cams carried thereby, a frameextending forwardly of and to the rear of said pivot stud and arrangedto swing concentrically thereto, a reciprocating plunger carried b-y theframe and including a yoke surrounding the said stud and the eccentriccams thereon, that part of the yoke to the rear of said eccentric camscomprising a cross-head for coaction with said eccentric cams, a guideconnection between said cross-head and said frame, a guide connectionbetween the plunger' and said frame, and a spring coacting with saidplunger to force said cross-head in a direction toward said stud andeccentric cams to normally cause said cross-head to engage both of saidcams when the parts are in the door closed position.
